Specification of Letters Patent.

Patented Apr. 114i, 191%.

Application filed March 5, 1912. Serial No. 681,744.

To all whom it may concern.

Be it known that 1, BURNHAM C. STICK- .YEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New J erscy, have invented certain new and useful Improvements in T ypelVriting Machines, of which the following is a specification.

This invention relates to means for feeding webs to the feeding-rolls of typewriters and other printing-machines, etc.

I support upon the table or framework of the machine a swinging frame, which has a connection to the. carriage of the typewriter or printing-machine, so as to swing as the carriage travels. The roll or rolls of paper are mounted on said swinging frame at points near the hinge or pivot thereof, so, that there is very little movement of said rolls at the letter feeding movement of the carriage, and hence the inertia of the rolls is not so serious an objection to the rapid operation of the machine as heretofore. The webs are led from the rolls upwardly and loopedover an inclined guide mounted 011 said swinging frame, and are thence led to the rolls of the typewriter. The inclined guide is preferably mounted to swing independently of the carriage, so as always to substantially take up the slack in the web.

In the accompanying drawings, Figure 1 is arear View of an Underwood typewriting machine, showing my improvements connected thereto. Fig. 2 is a plan of a hinged frame upon which the paper rolls or spools are mounted. Fig. 3 is a part-sectional eleration. showing the relation of my improved device to the typewriting machine.

The frame 1 of the typewriting machine rests upon a table 2. A. carriage 3, having a cylindrical platen or roll 4, travels upon tracks, of which one is seen at 5. The web is fed around the platen by the usual rolls 6, 7 The letter-feeding movement of the carriage is controlled by a mechanism of which a part is seen at 8. A roll or spool of paper 9 is pivoted at 10 to a frame 11, which is hinged or pivoted at 12 in a stationary bracket or support 13, resting upon the table 2 back of the typewriting machine and close thereto. The hinged frame 11 has an arm or arms 14, carrying a web 15 to receive carbon imprints of the typewritten matter; and a carbon roll 16 may be mounted upon an arm or arms 17, the carbon web being laid between the webs 15 and 9. thus forming a multiple web which is looped over a guide 18 and led down to the bight of the rolls 1, 6. The three webs are preferably assembled or passed between guide pins 19 on said arm or arms 14. The guide 18 may be in the form of a roll journaled upon a long pin or stud 2O projecting from a boss 21 formed upon the upper end of arm 22. which extends up from the frame 1.1 and this'arm may be connected by a link 22 to an arm 22*, which is fixed upon the carriage 3, so that the roll-carrying. frame will swing or vibrate upon the hinge 12 as the carriage moves to and fro; the travel of the carriage being generally less than the width of the web 9. It will be seen that the guide 18 is inclined upwardly, forwardly and sidewise from the arm or standard 22, in a position to take up the slack due to the twisting of the web from the original edge wise position at Fig. 1 tothe final flatwise position at said figure, when it is wrapped around the platen. By placing said guide substantially as shown in said figure, it is practicable for the web to extend downwardly and forwardly tangentially to the platen. and vertically down to the guide pins 19. There is also permitted a sufficient range of movement of the carriage to write entirely across the narrow web without danger of tearing it.

Preferably the arm 22, carrying the inclined guide'18, is swiveled, and it may also be provided with an arm 23 by which it may be turned, so that the guide roll 18 can be swung sidewise to accommodate the movement of the carriage and substantially take up the slack in the web at all times. This swinging of the roll is accomplished automatically; a pin 24 on said arm 23 engaging "a slot 25 in a plate 26, the latter fixed upon a an arm 27 projecting up from the fixed bracket 13. As the carriage travels in letterfeeding direction during the writing of a line on the web, the arm 22 is caused to turn slightly on its upright axis 28, so that the forward end of the guide roll 18 travels faster than the rear end, in the direction in which the carriage travels. The cam 25 may be so shaped and the guide 18 so placed that substantially all of the slack in the Web will be taken up. Therefore the web will travel true, and maintain its proper relationship to the platen, without danger of slipping or of injuring its edges, or of relative displacement of the members of the three-part.web.

The link 22 is pivoted to an ear upon the arm 9:2, by means of a universal joint 29, so as to accommodate the swinging motion of said arm 22 produced by the cam 25.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
